在使用NHibernate，您通过虚拟方式定义你的entites，和NHibernate将创建跟踪更改的对象的代理对象。

When using NHibernate, you define your entites with virtual methods, and NHibernate will create a proxy object that tracks changes to your object.

在起订量，框架会奇迹般地创造派生类型从一个接口或基类。例如

In Moq, the framework will magically create a derived type from an interface or a base class. e.g.

var mock = new Mock<IFoo>();
IFoo magicFoo = mock.Object;

这是真的很酷。如何将这些框架做呢？他们是否使用反射，泛型，某种动态编译的，还是其他什么东西？

This is really cool. How do these frameworks do it? Do they use reflection, generics, some kind of dynamic compilation, or something else?

我知道这些都是开源的项目，我可以去通过code洞穴探险，但是我想有一个简洁的答案在这里 - 可能与替代品的

推荐答案

起订量使用城堡动态代理，但是，只是认为这将是值得加入也有一些其他的框架，允许你创建代理对象。由于NHibernate的2.1还允许您使用以下任何一项：

Moq uses Castle Dynamic Proxy, however, just thought it would be worth adding there are also a number of other frameworks that allow you to create Proxy objects. As of NHibernate 2.1 it also allows you to use any one of the following:

每个这些项目都有他们是如何做到这一点的一个简短的解释，这是希望的那种，你要寻找的答案。

Each of these projects has a brief explaination of how they achieve this, which is hopefully the kind of answer you're looking for.
